Error when opening the Application (APNX-1-4198-000)

Certified Senior Developer

Hello All,

I'm facing this issue while opening the application which contains CDT's, groups and DS.

The System Has Encountered an Error

HTTP Code: 500 APNX-1-4198-000 Error Evaluating UI Expression Expression evaluation error [evaluation ID = a5eb9:bc758] : Appian object error. Details: Failed to execute query in thread for: EngineBackedQueryExecutor [queryKey=DESIGN, typeIds=[23, 80, 200], transformTypeIds=[23, 80, 200], refClasses=[class com.appiancorp.type.refs.ProcessModelRefImpl, class com.appiancorp.type.refs.DatatypeRefImpl, class com.appiancorp.type.refs.ProcessModelFolderRefImpl], reducedExecutor=[ReducedExecutor extended-process-design-service:Process Model,Data Type,Folder (Process Model)]]

Please let me know how to resolve this issue.

Thank You,

Sneha.

    Just troubleshooting here.

    Can you elaborate more on what you can and cannot open/view?

    Can you check the system logs for any more details on this error?

    Can you export the application (without entering it, as you say it's not possible) and perform an import analysis to explore potenital issues?

    Did you scan the topics with similar errors to perhaps find a similar sitaution as yours? There are a few topics.

    Since what action does the error occur?
